Embodiment Construction
[0020] Include the following steps:
[0021] (1) Using the finite element method, based on the modal, steering column stiffness, static load test, lateral crush test and ODB test conditions, a preliminary design is carried out considering space constraints and process constraints, and only the beam 3 section is designed , no ribs are arranged; the 3-section of the beam adopts a U-shaped structure, and the weight of the driving side is greater than that of the member side, so the driving side section is larger than the member side section;
[0022] (2) Use the finite element analysis software CATIA to conduct structural topology optimization, including size optimization and shape optimization, to find weak parts of structural rigidity. The analysis shows that the rigidity between the mounting bracket 2 on the driving side of the vehicle body and the floor connecting bracket 10 is weak , it is necessary to use the crossbeam reinforcement board 4 to strengthen, the crossbeam rein...

The invention relates to a production method of a beam assembly of a continuous glass fiber board enhanced plastic instrument board and belongs to a production method of a beam assembly of a plastic instrument board. A weak part of a structure is obtained by a finite element topological optimization method and an all-plastic panel assembly is locally enhanced by means of local enhancement of a continuous glass fiber board, so that it is uniform to stress and stress concentration is reduced. The density (1700 kg / m<3>) of the continuous glass fiber board is far smaller than that of a steel insert and the continuous glass fiber board is light in weight. The continuous glass fiber board can be melted to a plastic material, so that the continuous glass fiber board is high in reliability. As a result of high degree of automation in design of a plastic part, local enhancement is carried out according to a finite element analyzing result, so that the integral stress is uniform and the performance is excellent. Compared with the beam assembly of the all-plastic instrument board and the beam assembly of the instrument board with a metal insert, effects of being excellent in performance, light in eight and easy to achieve structure are achieved.
Description
technical field [0001] The invention belongs to a production method of a plastic instrument panel crossbeam assembly, in particular to a design method for a plastic instrument panel crossbeam assembly reinforced by a continuous glass fiber board, which is applicable to the field of new energy vehicles. Background technique [0002] With the extensive promotion of new energy vehicles in the country, the lightweight of parts has become the focus of design and development of various OEMs. The instrument panel beam assembly carries the steering column, steering wheel and instrument panel assembly. Driving and riding comfort, so the plastic instrument panel beam assembly should have sufficient rigidity and strength. [0003] Due to the space limitation of the traditional all-plastic instrument panel beam, the stiffness and modal performance of the steering column installation point cannot meet the requirements; the plastic instrument panel beam with metal inserts is heavy, which ...
